6-8 swap, trans dapt swap kit, TTI header issues?

We had a '72 Demon in the shop with a slant K and a Trans Dapt mount kit and issues fitting the TTI 340W2-17835 headers we sold him. He also had a deep sump Milodon pan that had fitment issues.

Cliff's Notes version, engine was not located properly per the TTI measurements. It was off in multiple planes (X, Y and Z). Took a lot of fiddling with the Trans Dapt kit, a second set of isolators, passenger isolator rotated at a funny angle, a couple of the Schumacher shims (we had them in stock), and a notch in the flange on the K to clear the corner of the oil pan.
